Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a novel plastic housing for power tools. Background Technology

[0002] New power tools are developed using the latest technologies, achieving breakthroughs primarily in battery technology, motor control, and intelligent features. They are characterized by high efficiency, portability, and intelligence. Most designs are mainly used for fixing components such as screws.

[0003] In the prior art, such as Chinese Patent No. CN221020860U, a plug-in type plastic housing for an electric tool includes an outer shell. Pressure plates are movably connected to the front and rear sides of the inner wall of the outer shell. A screw is rotatably connected to the right side of the pressure plate, and the right end of the screw penetrates the side wall of the outer shell. A movable block, a pressure block, a crossbar, and a spring are provided. After the handle of the electric tool is inserted into the housing, a handwheel can be turned to rotate the screw, causing the screw to push the pressure plate to move. The pressure plate's compression secures the handle to the inside of the housing. Subsequently, pressing the movable block activates the pressure block to press a switch, thus driving the electric tool. Furthermore, when working at heights, the operator can hold the bottom outer side of the housing and press the movable block to achieve the same purpose of pressing the switch. The degree of pressure can be adjusted according to the actual situation, resulting in better practical performance.

[0004] While the above solution has the advantages mentioned above, its disadvantages are that the screw design used to fix the power tool body is prone to jamming due to rust after long-term use, thus reducing the efficiency of the operator. In addition, when it is necessary to replace different tool heads, the design requires direct contact with the hot tool head after use, which can easily cause burns to the operator.

After placing the power tool body inside the plastic housing, the curved control plate is released. Spring one uses its elasticity to push the fixing plate back into panel one, thus fixing the position of the power tool body. Pulling the limiting post upwards along the inner wall of slot three causes one end to be pulled out of the flipping curved plate, releasing the flipping restriction on the curved plate. The flipping curved plate then flips outwards under the action of spring two, at which point panel two can be operated. In this design, functional components are used to fix the power tool body, and the movable flipping curved plate facilitates the use by the operator, providing more comprehensive protection for the power tool body.

[0048] 2. In this invention, pulling the pull plate to one side horizontally stretches the spring four, causing the fixed axis to move to the same side and thus detach from the fixing buckle. At this point, the tool head is movable. Flipping the power tool body allows gravity to dislodge the tool head from the two concave clamps. The replacement tool head is placed between the two concave clamps until the fixing buckle aligns with the fixed axis. Releasing the pull plate allows the fixed axis to engage with the fixing buckle under the elastic force of the spring four. This design uses a fixing component to secure the tool head, and the unique assembly / disassembly design eliminates the need for direct contact when replacing the tool head, preventing direct injury to the operator.

[0064] Meanwhile, the functional components are located on the plastic housing 2, which can fix the power tool body 1 inside the plastic housing 2 without affecting the user's operation.

[0065] It should be noted that the shape of tool head 5 includes, but is not limited to, cross shape, plum blossom shape or triangular shape; this design uses the straight shape.

[0066] In this redesign, the new power tool plastic housing also includes: panel one 101 and panel two 102.

[0067] Among them, the auxiliary panel 101 is opened on one side of the power tool body 1.

[0068] Meanwhile, the second panel 102 to be used is located on the other side of the power tool body 1.

[0069] It should be noted that the surface of panel 2 102 has multiple touch buttons.

[0070] As examples, in this embodiment, the functional components include: slot 1 201, fixing plate 203, two track posts 204, spring 1 205, slot 2 3, spring 2 303, slot 3 304, and limiting post 305.

[0071] Among them, the slot 201, which serves as a space, is opened on one side of the inner wall of the plastic shell 2, and two auxiliary holes 202 are opened in the slot 201.

[0072] Meanwhile, the fixing plate 203, which plays a fixing role, is embedded in the slot 201.

[0073] It should be added that the auxiliary hole 202 penetrates the side wall of the plastic housing 2.

[0074] In addition, the two track posts 204 that serve as the connection are embedded in the two auxiliary holes 202, and a curved control plate 206 is installed on one side of the two track posts 204.

[0075] Furthermore, the elastic spring 205 is installed on one side of the outer wall of the plastic housing 2.

[0076] It should be noted that one end of the track column 204 is connected to the fixing plate 203, and the other end of the spring 205 is connected to one side of the curved surface control plate 206, which is located outside the plastic housing 2.

[0077] In this design, a second slot 3 is provided on one side of the plastic shell 2, and a rotating curved plate 301 is rotatably installed in the second slot 3. The rotating curved plate 301 has a rotating shaft groove 302.

[0078] In order to make the flip plate 301 automatically flip outward, a spring 303 is installed and embedded in the rotating shaft groove 302.

[0079] It should be noted that the two ends of spring 2 303 are connected to the upper and lower sides of the inner wall of slot 2 3 respectively, and spring 2 303 is a special torsion spring, which can control the flipping plate 301 to automatically flip outward.

[0083] In this embodiment, the curved control plate 206 is pulled to one side in the horizontal direction. With the connection of the two track posts 204, the fixing plate 203 moves to the same side with the curved control plate 206 and is embedded in the slot 1 201. After the power tool body 1 is placed in the plastic housing 2, the curved control plate 206 is released. The spring 1 205 uses its elasticity to push the fixing plate 203, so that it returns to the panel 1 101, thereby fixing the position of the power tool body 1. The limiting post 305 is pulled upward along the inner wall of the slot 3 304, so that one end of it is pulled out from the flipping curved plate 301 and the flipping restriction on the flipping curved plate 301 is released. The flipping curved plate 301 is flipped outward under the action of the spring 2 303. At this time, the panel 2 102 can be operated.

[0084] Example 2:

[0085] Please see Figures 1-8 Based on Example 1, this example provides a novel plastic housing for power tools, the specific concept of which is as follows:

[0086] The new power tool's plastic housing also includes: two uprights 4 and a fixing assembly.

[0087] Among them, the two supporting plates 4 are located on the top of the power tool body 1.

[0088] Meanwhile, the fixed component is located on the top of the power tool body 1, which can be used to assemble and fix different types of tool heads 5.

[0089] As examples, in this embodiment, the fixing components include: a pull plate 401, two springs 403, two upright plates 404, and two T-shaped columns 405.

[0090] Among them, the pull plate 401 that initiates the pulling action is located on one side of the upright plate 4, and a fixed shaft 402 is installed on one side of the pull plate 401.

[0091] Meanwhile, two springs 403, which provide elasticity, are installed on one side of the pull plate 401.

[0092] It should be noted that the fixed shaft 402 passes through the two upright plates 4 and is embedded in the fixing buckle 501, and the other end of the spring 403 is connected to one side of the upright plate 4.

[0093] In addition, two vertical plates 404, which also serve a supporting function, are installed on the top of the power tool body 1.

[0094] Furthermore, the two T-shaped columns 405 that are used for pulling are respectively embedded in the upright plate 404. One end of the T-shaped column 405 is equipped with a concave clamp 406, and a spring 407 is sleeved on the concave clamp 406.

[0095] It should be noted that the concave clamp 406 is located on one side of the tool head 5, and the two ends of the spring 407 are connected to one side of the vertical plate 404 and one side of the T-shaped column 405, respectively.

[0096] In this embodiment, the pull plate 401 is pulled to one side in the horizontal direction, so that the spring 403 is in a stretched state and drives the fixed shaft 402 to move to the same side, and then pulls it out from the fixed buckle 501. At this time, the tool head 5 is in a movable state. The power tool body 1 is flipped over, and the tool head 5 is dislodged from the two concave clamps 406 by gravity. The replacement tool head 5 is placed between the two concave clamps 406 until the fixed buckle 501 corresponds to the fixed shaft 402. The pull plate 401 is then released. Under the elastic action of the spring 403, the fixed shaft 402 is driven by the pull plate 401 and embedded in the fixed buckle 501.

[0097] Working principle:

[0098] When it is necessary to fix the power tool body 1, pull the curved control plate 206 to pull it to one side in the horizontal direction. This will drive the two track posts 204 to move to the same side and drive the fixing plate 203 to move synchronously, so that it is embedded in the slot 1 201. The spring 1 205 is in a stretched state under this movement. Place the power tool body 1 in the plastic housing 2, release the curved control plate 206, and under the elastic action of the spring 1 205, the fixing plate 203 returns to the panel 1 101, thus completing the position fixation of the power tool body 1. When it is necessary to operate the power tool body 1, pull the limiting post 305 to move it upward along the inner wall of the slot 3 304. One end of the limiting post 305 disengages from the flipping curved plate 301, and the spring 3 306 is in a compressed state. With the limiting post 305 no longer supporting it, the spring 2 303 drives the flipping curved plate 301 to flip outward, so as to control the panel 2 102.

[0099] When the tool head 5 needs to be replaced, pull the pull plate 401 so that it moves to one side in the horizontal direction. Under this movement, the spring 403 is in a stretched state. The fixed shaft 402 moves to the same side under the drive of the pull plate 401 and disengages from the fixed buckle 501, thereby releasing the restriction on the tool head 5. At this time, invert the power tool body 1 so that the tool head 5 can fall out from the two concave clamps 406 under the action of gravity. Place the new tool head 5 between the two concave clamps 406. The two concave clamps 406 provide auxiliary support on both sides of the tool head 5 under the action of the spring 407. When the fixed buckle 501 corresponds to the fixed shaft 402, release the pull plate 401. The spring 403 uses its own elasticity to drive the fixed shaft 402 to embed into the fixed buckle 501.
